BB2 - Brian was a worthy winner. I only really supported him, Helen and Narinder at the time.
BB3 - I was an Alex fan. Not just for the Hot Chocolate moment, but he was generally a cool guy, unassuming, and haaaaaaaawt.
BB4 - All of my favourites left before the final (Sissy, Federico, Tania) but I really liked Ray. Cameron is the worst winner ever, IMO.
BB5 - I really wanted Nadia to win. I can't think of another candidate. Dan was rather lovely though.
BB6 - Derek, undoubtedly. I felt a huge sense of outrage upon his eviction before the final - especially against Eugene. On rewatching, he wasn't as much of a key character as I thought: not one to snog randomly or get drunk. But that said, he was fantastic: power-crazy, argumentative, almost regal. I would've been happy with Kemal, Makosi, Science or Kinga winning (Kemal for the 'redemption' factor [had Nadia not won the year before, I feel he would have won], Makosi for pure entertainment, Science for consistent independent thought and underdog status, Kinga because the other finalists were appalling/hated.)
BB7 - I was supporting Aisleyne and Richard in the final. Richard had provided great entertainment with the nominations and was, despite Imogen, a generally nice guy. Aisleyne came out with priceless lines and probably had the biggest ordeal in the house.
BB8 - I supported Carole throughout, much to the chagrin of TiBB at the time. I don't think she was right for the House - too concerned with domestic maintenance and mothering, in a house full of sluts and wannabes. But she was a rock, always caring, and provided some entertainment (chasing Ziggy around)
BB9 - I lost all interest after the evictions of Rebecca, Mario, Luke and Belinda. It's the only time I've supported a group of people who were dominated by a group of total dickheads (Rex, Darnell, Mohamed). Of the final I wanted Sara to win, and I was delighted she beat two of said dicks.
BB10 - didn't really watch much because it was too long and too contrived, but Angel, Siavash and Sophia were my favourites. Didn't care who won as long as it wasn't Charlie, Lisa or David. Absolutely disgusting specimens.
BB11 - Again, lost interest halfway through (with the predictable evictions of big characters like Sunshine, Ben and the disastrous quadruple) and I really only supported Ben, Sunshine and Corin throughout. The final was absolutely appalling. Mario? Hahahahaha.
